AUToMATicsAsi-i LIFTER AND LOCK.

sPEcIrcATIoN arming part of Letters Patent No. 278,323, dated May 29, ieee. Application filed January 17, 1883. (No modeh) To all whom t'ttnoy concern Beit known that I, CHARLES W. ELLIOTT, of Boston,finithe State of Massachusetts,have invented certain new and useful Improvements in Sash Lifters and Fasteners,of which the following is a specification.

My invention relates to that classof combined sash lifting and fastening devices in which the lifter is movable up and down upon Io the sash within prescribed limits, and operates,

when used either to raise or depress the sash,

to automatically draw the bolt by which the sash is locked in place; and it consists in an improved arrangement and combination of I devices for the purpose, which may be generally stated to consist in combining with the verticallydmovable lifter-handle the horizontally springcontrolled locking-bolt, by means of a connection consisting of a V- groove on zo the one and a pin on the 4other to engage and traverse said groove, whereby the traversing movement of the pin (caused by raising or pressing down the lifter) in either direction from the `apex or elbow of the groove shall cause the'bolt to be drawn and the sash unlocked.

The mechanism in which the improvement is embodied is simple, effective, cheap, and `readily made and applied. l

In the accompanying drawings, Figure 1 is a front elevation of the fastener and lifter in place on a sash. Fig. 2 is a like view, partly in section, with the parts in the position they occupy when the bolt is drawn. Fig. 3 is a longitudinal horizontal section, and Fig. 4 is a transverse vertical section, of the device, to-

. gether with the sash-rail to which it is attached.

Ais thelifter, consisting of a plate mounted so as to slideup and down between gibs or 4o dovetailed guides t on abase-plate or scutchcon, B. A pin, b, projecting from B into a vertical slot, c, in the lifter, limits the extent of movement of the latter. The lifter-plate is provided with a horizontal projection, A', constitutin'g thwe handle by which it Vcan be raised or depressed. ,y

Uponthe rear of base B is a horizontal cylindricalcase, C,closed at its outer end and intended to receive the rear endof the bolt- 5o socket D, which is supported in the case C' and a guide, forth.

A spiral spring, S, within the case O, encircling the stem of the bolt-socket, and confined between a flange or pin on that stem and the outer closed en d of the case, serves to push the bolt-socket forward in a direction which shall cause the bolt to protrude from the sash.

rlhe bolt, as shown at E, is a cylindrical rod or stem provided with a screw-threaded end which screws into the internally-screw-threaded end ofthe socket D. ThepartsD and E, when in use, are virtual] y one, and the object of making them separable is to facilitate the fitting of the device to the sash. From the stem of the bolt or bolt-socket projects forward a pin or stud, e, which passes through a horizontal slot, f, in the base-plate, and enters and engages V-slot g in the lifter-plate.

The normal postion of thepin is at the elbow or angle of the slot g, to which position it is brought by the stress ofthe spring S, the plate Aadapting itselt` to thisposition, in which the d, so that it can slide back and bolt will be pressed forward and protruded from the side of the sash. It will be seen that if the lifter A be moved from this position in one direction or the other, one or the other of the inclined faces of the groove against which the pin Works will act to gradually force back the pin, and to thus draw back the bolt.

To apply the device to the sash F, the baseplate B and parts carried by it, with the eX- ception of the bolt E, are applied tottlie lower rail of the sash, in the face of which a mortise or recess is cut of a size sufficient to receive the parts carried onthe back of the baseplate, and to allow them requisite freedom ofmovement. The base is secured to th'e sash by screws fr, or other suitable means. Through a hole bored from one'side of the sash into the recess or Inortise cut in the sash-front for `receiving the bolt-socket the bolt E is inserted, and is fitted and screwed into the socket D, after which the device is ready for use, it being of course understood that any suitable number of holes, ytoreceive`the projecting end of the bolt are provided in theportion of the contiguous frame G in which the sash slides. Under these circumstances it will be seen that so long as thelifter is untouched the rco .2v y v 278,323

bolt will remain protruded, and will thus lock the sash to the frame. So soon, however, as it is attempted to raise or lower the sash by means of the lifter, the first effect Willbe Y,to 5 move the lifter in one direction or the other independently of the sash, with the result of moving the pin back from the elbow of the groove g along one or the other of the rearl wardly-slanting faces of the groove, and cono sequently of drawing the bolt,-after which the sash can be freely moved. The moment pressure is removed from the lifter, the bolt Will, by the stress of its now released spring, seek and find the hole y which may be opposite to it?, and the sash Will again be locked in place.

I remark that the bolt-work may carry the V-groove, and the lifter-plate the pin to work in said groove. This, however, would be an obvious reversal of the arrangement shown, 2o and would not be so convenient.y

What I claim, and desire to secure by Let ters Patent, ism- 1. The sliding sash-lifter, in combination with the longitudinally-reciprocatin'g springcontrolled sashbolt, provided the one with a z5 V-groove and the other with a pin which engages said groove and is normally held by the stress of the spring at the apex or elbow of said groove under the arrangement and for joint operation as hereinbefore set forth.

' 2. The base-plate and the sliding lifter, the

spring-receiving case, the spring, and the bolt-- socket mountedon said base-plate,asdescribed,

in combination with the bolt detachably connected with said socket, and a pin in the bolt- 55 stem, which enters and engages a`V-groove in the sliding lifter, these parts being constructed and arranged for joint operation as hereinbefore set forth.
